Metal Detection-Prototype 4

We decided to measure the voltage from the metal detector from Prototype 3. As we suspected it was not high enough to move the flexinol wire. Here we show it at it's highest,
0.09 Volts.

We purchased a new metal detector with a larger coil and which runs on two 9V batteries. We immediately tested the voltage from the new detector. Our highest result was 8.2 Volts, much larger than the previous.
